我对 Ubuntu 还不熟悉。去年冬天我们家的电脑硬盘坏了，所以有了新硬盘，我就不再换 Windows 了，因为 Windows 或多或少只是用来查看邮件、上网和玩游戏。所以，我以前用过 ubuntu，喜欢它。总之，长话短说，我从 18.10 升级到 19.04，出现了几个错误。电脑运行良好，但似乎无法安装其他软件。试图让 flash 工作，这样我的妻子就可以玩拼字游戏了。我不认为这是硬件问题。我重启了几次电脑，没有问题。这是升级到 19.04 后出现的问题。升级过程中出现了几个错误。一个是关于 xscreensaver 被锁定，需要解锁之类的。我不记得其他的了。除了无法安装其他任何东西外，它似乎运行正常。尝试安装时出现以下信息：

任何帮助将不胜感激。
谢谢
